"Google's Motorola Mobility unit said it filed a new patent-infringement case against Apple claiming that features on some Apple devices, including the Siri voice-recognition program, infringe its patents. The complaint at the U.S. International Trade Commission claims infringement of seven Motorola Mobility patents on features including location reminders, e-mail notification and phone/video players, Motorola Mobility said yesterday. The case seeks a ban on U.S. imports of devices including the iPhone, iPad and Mac computers." Can anybody explain to me how this is a new suit when Motorola and Apple have been wasting tax money and court resources for years now?
